An automobile radiator such as the Volvo 760 radiator is the most important component of the automobile engine cooling system. It is the central functioning unit that is almost entirely responsible for the dissipation of heat from the water coolant. A radiator is a flat metal box that is typically located in the front portion of the engine compartment. It is located just behind the grille and radiator fan. Although box-like in shape, the radiator closely resembles more a sliced bread rather than a cargo box. Its thin structure enables it to precisely fit in between the engine block and the automobile grille.
Engine cooling systems cannot function without the coolant that circulates its system. The coolant carries heat from the engine and releases this heat to the outside environment. A radiator such as the Volvo 760 radiator is the one that is directly responsible for the release of heat from the coolant. The coolant begins its circulation in the coolant reservoir or water tank. The water tank is typically a separate container found at the much cooler area of the engine compartment. The water tank contains the main supply of coolant. The coolant is actually a combination of water and ethylene glycol as anti-freeze.
An anti-freeze such as the ethylene glycol is necessary to prevent the coolant from freezing during cold weather situations such as blizzards. If the water becomes frozen, it will damage the cooling system of the engine. Some parts may even crack in the process. A simple centrifugal water pump draws out the coolant from the water tank. Atmospheric pressure assists in the drawing of coolant because a partial vacuum state is created inside the water pump. The coolant then flows inside the engine block, absorbing excess heat. The water coolant then exits the engine to circulate in the radiator such as the Volvo 760 radiator.
